Make es run, now and on reboot:

systemctl daemon-reload
systemctl enable elasticsearch

Connect to es and add the "map" index, with our datatype:

curl -XPUT "localhost:9200/map" --data @maptype.json

If you need to remove the index and start over, try this:

curl -XDELETE "localhost:9200/map"
curl -XPUT "localhost:9200/map" --data @maptype.json
